MADISON, Wis. (AP) -- Wisconsin Gov. Scott Walker's spokesman and two others have been granted immunity in an investigation of the Republican governor's current and former aides.
Retired Waukesha County Judge Neal Nettesheim said Friday that he granted immunity to Walker spokesman Cullen Werwie, Wisconsin and Southern Railroad spokesman Ken Lucht and Milwaukee County Republican Party official Roseann Dieck.
Nettesheim said they were granted immunity at different times, more than 60 days ago, during the course of a secret John Doe investigation.
Nettesheim is overseeing a secret investigation into people who worked for Walker when he served as Milwaukee County executive.
Werwie had no comment when reached by AP. Dieck and Lucht did not immediately return messages seeking comment late Friday.
The Milwaukee Journal Sentinel first reported the granting of immunity on Friday.
